1, Heat shrink machine daily work, the blade must use steel wire brush, heat shrink machine stripping agent for cleaning and maintenance. Moving parts must often add lubricant.
  2, Heat shrinkable machine blade contact surface is foam silicone rubber strip to protect the good, if it is found that the outer layer of high temperature cloth burning, should be replaced immediately.
  3, The replacement of shrink machine'sealing and cutting blade, fixed grip loosen the sealing cutting knife, remove the seal cutter, knife cleaning slot (note not to damage the knife groove, a replacement can be used under the old blade as a cleaning tool), install the new blade, placing groove and pressed, knife tablets fixed on both ends of the blade fixing chuck, a pressing spring, a fixing screw.
  4, Heat shrink machine if sealing and cutting machine can seal cutting film or sealing and cutting effect is not good, there may be the following reasons:
  A heat shrink machine, sealing and cutting blade ends no voltage (seal cutting transformer damage or connection open circuit, reconnect or replacement).
  B heat shrink machine, power supply voltage is too low (the input power supply voltage regulator configuration).
  C heat shrink machine, sealing and cutting time regulating improper or time relay damaged (re adjust or replace).
  D, heat shrink machine blade incision surface is not flat (cleaning cutter groove, re install the blade).
  E, heat shrink machine blade has been broken or bad (adjust or replace the blade).
